I everyone, I have a complicated situation so please bare with me for a minute. Years ago our garage door started to go up by its self. I was thinking about replacing the opener but when I looked online at some of the reviews I decide to just pull the emergency release cord and manually pull the door up and down. I closed it with chains tied on the frame on the inside Anyway this morning i find my garage door pulled up about 4 inches The door was so jammed up that I had to take the lock off the chain but I couldn't unroll the chain from where i had it tied so I had to use the claw part of the hammer to pull loose the chain. It was so pulled up the metal bar that the door slides up on was bending. When I finally got the chains off the door it went up a inch or so more and I couldn't get it back down. I pulled the emergency release cord and the door could be pulled down a little but stoped so I had to pull the cord again, finally I pulled the cord and taped it and used some clips to hold it in the release position , Anyway my question is this could the Emergency Cord some how reset its self and the motor malfunctioned again and the door tried to open but was stopped by the chains?
